Murder is a game that Randi Sanderson knows far too well, but at least she's playing on the right side of the law. Being half-archangel and half-vampire makes her one of Jacksonville Sheriff Office's best detectives and a suspect's worst nightmare.

When she arrives at the scene of her next case, it's obvious this murder isn't a typical human crime of passion or rage. As a powerful hybrid, Randi can sense something is off, and not just because the body was dumped in a church parking lot. Luckily, her many gifts include the ability to dig up dirt on anyone.

This time, getting to work won't be so simple. Surprised by a new partner, Randi knows her life is about to get a little more complicated. There's a reason she doesn't work with others. To the outside world, she's just a police detective and single mom, but the reality is she has a secret identity to keep.

With the case taking a dark turn and her new partner obviously keeping secrets of his own, the last thing Randi needs is more trouble. So when the angelic and demonic factions start bidding to hire her to kill other supernatural beings just like herself, she patently refuses. The rogue hybrids known as The Shade are none of her concern, and she isn't interested in becoming an assassin.

But when she finds herself in the middle of her own case with The Shade coming for her, she must reconsider. The half-angel, half-demon miscreants won't stop until they're dead or they have what they truly want: Randi's son.
